Answer: A

Explanation:

When adjusting the Adaptive Flash Cache (AFC) configuration in HPE 3PAR StoreServ, particularly when increasing the cache size, the correct procedure involves first removing the existing flash cache for all Virtual Volumes (VVs). After this step, you should recreate the flash cache to reflect the new increased capacity. This ensures that the system properly recognizes and utilizes the additional cache space, optimizing performance according to the new configuration.
